We get the following compile errors if EXTCON is enabled as a module but this driver is builtin: drivers/built-in.o: In function `qcom_usb_hs_phy_power_off': phy-qcom-usb-hs.c:(.text+0x1089): undefined reference to `extcon_unregister_notifier' drivers/built-in.o: In function `qcom_usb_hs_phy_probe': phy-qcom-usb-hs.c:(.text+0x11b5): undefined reference to `extcon_get_edev_by_phandle' drivers/built-in.o: In function `qcom_usb_hs_phy_power_on': phy-qcom-usb-hs.c:(.text+0x128e): undefined reference to `extcon_get_state' phy-qcom-usb-hs.c:(.text+0x12a9): undefined reference to `extcon_register_notifier' so let's mark this as needing to follow the modular status of the extcon framework.

Revert "phy: Add USB3 PHY support for Broadcom NSP SoC"

2017-03-09T09:59:44Z

This reverts commit d7bc1a7d41bf ("phy: Add USB3 PHY support for Broadcom NSP SoC") as we already have driver for this PHY (shared by NS and NSP). It was added in commit e5666281d9ea ("phy: bcm-ns-usb3: new driver for USB 3.0 PHY on Northstar"). Instead of adding separated driver & duplicating code we should work on improving existing (old) one. Thanks to work done by Broadcom we know there is MDIO bus we weren't aware of & we know register names which makes initialization more clear. This is very valuable info and we should work on using it in existing driver afterwards. Acked-by: Jon Mason Signed-off-by: Rafał Miłecki

phy: phy-exynos-pcie: Add support for Exynos PCIe PHY

2017-02-21T13:48:42Z

Add support for Generic PHY framework about Exynos SoCs. Current Exynos PCIe driver doesn't use the PHY framework, which makes it difficult to upstream the other Exynos variants because of different PHY registers. Move the codes relevant to PHY from Exnyos PCIe driver to PHY Exynos PCIe driver.

phy: qcom-ufs: Suppress extraneous logging

2017-01-27T07:36:53Z

The error paths of the common qcom-ufs functions for registering the phy, acquiring clocks and acquiring regulators all print specific error messages before returning an error, so there is no value in printing yet another - more generic - message when this occur.

phy: qcom-ufs: Remove -always-on property

2017-01-27T07:36:52Z

The fact that a regulator is always-on is a property of the regulator, not a specific consumer. Implementing this in the driver leads to a system behaviour that is dependent on if the Qualcomm UFS PHY was ever (partially) probed. If the specific regulator should be always on in a particular device, mark it so by specifying "regulator-always-on" in the regulator node.
